Hi-Tech, microprocessor based correctors with LCD display. They are suitable for setting 7 or 12 capacitor groups. These correctors are metering the parameters in all three phase and the interference happens accordingly.
The metering of values is on analyzer level, the different levels capacitor power can be adjusted independent. In manual mode the user can control the number of capacitor groups. In automatic mode, the switching of capacitor groups takes place according to needed capacitor power and pre-adjusted parameters.
During rating process the switching of the levels follows a complex algorithm according to adjusted power factor value and level, protecting the capacitor groups and the switching contactors from run-down. The device has a potential free alarm output and it is programmable with front panel pushbuttons. The cooling is getting active according to pre-adjusted and memory stored level when the capacitor’s temperature is rising up. The alarm output’s active state is displayed by front panel LED.
